Rolling Probe Electrochemical Impedance System for Reinforced Concrete ID: 2015-009

An innovative system for rapid and accurate electrochemical impedance data acquisition on reinforced concrete structures.

Technology Overview

This technology introduces a rolling probe system designed to significantly expedite the acquisition of electrochemical impedance data on reinforced concrete structures, such as bridge decks. By employing large-area reference electrodes and a conductive liquid spray, the system circumvents the need for direct electrical connections to rebar, thus enabling faster, more efficient data collection. The system's truck-based implementation and integration with differential GPS for precise location mapping enhance its utility for large-scale infrastructure assessments.

Key Advantages

• Significantly reduces data acquisition time from minutes to seconds per location
• Eliminates the need for cumbersome direct rebar connections
• Enhances data accuracy through the use of a conductive liquid spray
• Facilitates large-scale operations with truck-based implementation

Problems Addressed

• Time-consuming process of electrochemical impedance data collection on reinforced concrete
• Difficulty in establishing electrical connections to rebar for impedance measurements
• Challenges in rapidly acquiring accurate impedance data over large surface areas

• Infrastructure maintenance and assessment for bridge decks and other reinforced concrete structures
• Real-time monitoring and prioritization of rehabilitation efforts for aging infrastructure
• Large-scale infrastructure health mapping and analysis
